Inthe annexed drawing, -the ligure is a side elevation, partly insection.

-A represents the window-frame, the side pieces ot' which are made eachof one single piece, with vertical grooves on the inner sides, toreceive the sa-shes B and C, thus dispensing with the nailing on of theusual strips. For the purpose of inserting and removing v the sashIthere is a recess, a, made in the inner -side ot' one of the side piecesof the frame, and this recess is closed by blocks or pieces D D,constructed to overlap each other, as .shown in Fig. 1, and fastened bya single screw, b. By removing this screw the blocks may be taken out,disclosing the recess a, when either sash may be pressed into saidrecess suflicient to clear the groove on the opposite side, and can thenbe taken out. The sash are inserted in the same manner, and the blocksthen fastened in place.

. Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-
